TYPES OF CHEMICAL REACTIONS
SYNTHESIS REACTION
Synthesis Reaction - two reactants combine to make a larger product
HCl(g) + NH3(g) NH4Cl(s)
DECOMPOSITION REACTIONDecomposition Reaction - a large molecule breaks down to form two or more simpler products
DECOMPOSITION REACTION
SINGLE DISPLACEMENTSingle Displacement - an element displaces another element in a compound, producing a new compound and a new product
Cu(s) + 2AgNO3(aq) Cu(NO3)2(aq) + 2Ag(s)
DOUBLE DISPLACEMENTDouble Displacement Reaction - elements in different compounds displace each other, producing two new compounds
AgNO3(aq) + NaCl(aq) Na(NO3)(aq) + AgCl(s)
COMBUSTION REACTIONCombustion Reaction - rapid reaction of a substance with oxygen to produce oxides and energy; burning
Hydrocarbon - compounds that contain only hydrogen and carbon
Hydrocarbons often react with oxygen in combustion reactionsEnergy source for vehicles etc...
COMPLETE COMBUSTIONComplete Combustion - a combustion reaction of hydrocarbons that uses all the available fuel and produces only carbon dioxide, water, and energy ; occurs when oxygen supply is plentiful
i.e. CH4(g) + 2O2(g) --> CO2(g) + 2H20(g) + energy
INCOMPLETE COMBUSTIONIncomplete Combustion - a combustion reaction of hydrocarbons that may produce carbon monoxide, carbon (soot), carbon dioxide, water, and energy; occurs when oxygen supply is limited
i.e. C4H10 + 5O2(g) --> 2CO2(g) + 5H2O + CO + C(s) + energy
